- daily-evaluation nutzt die Jahre 2011/2012 statt 2001, damit der Job nicht die Daten von autopilot und reminders liest und verändert. - throttler: app.listen(0) einmal je App statt eines Servers je Anfrage (ECONNRESET bei 40 parallelen Anfragen). - outbox-claims: 120 s Zeitlimit für 2000 sequentielle Anweisungen. - migration-harness: eine `migrate deploy` zur Zeit über eine eigene Advisory-Sperre (P1002 bei parallelen Migrations-Suites). - authority-notices und authority-notices-herd laufen über exclusive-suite nacheinander; Herd-Wiederholung räumt eigene Entwürfe.
